Just tried menu again, always makes horizontal menus, so I tried create a number of single menus stacked vertically, issue is the menus drop down over the top of the others below, so guess still looking to find away to do this :o/

I have tried this using Block, not exactly the effect I was looking for, it does help to hide the other parent menus, but can also make selecting every other one not possible until stop selecting any menu item, have played around with menu control, but still not what I'm looking for sadly :(
